F. EUGENE J EANJ AQUET, OF DETROIT, MICHIGAN, ASSIGNOR OF ONE-HALF TO JOHN F. GUILLOZ, OF SAME PLACE.

COLTER-CLEANER.

SPECIFICATION forming part of Letters Patent No. 310,283, dated January 6,1885.

Application filed February 15, 1S84. (No model.)

To all 1072,0722, it may concern.-

Beit known that I, F. EUGENE J EANJAQUET, of Detroit, in the county of Vayne and State of Michigan, have invented new and useful 5 Improvements in Collier-Cleaners; and I hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to a new and useful improvement in colter-cleaners, intended to form an improvement on the colter-cleaner patented to me November 13,1883,No. 288,442.

In the drawings, which form a part of this Specification, Figure 1 is a side elevation of a plow of ordinary construction to which my device is applied. Fig. 2 is a detached detail view of the cleaner-hook.

Ais theplow-wheel, 13 its adjustable standard, O the plow-bcarn, and D the colter, all

of known construction and operation.

E is a pitman, consisting of the parts a and 'I), which are firmly and adj ustably secured together by means of the bolt and nut c. The

I 2 rear end, h, of the part a of the pitlnan is bent downwardly, and is secured to the plow-wheel by means of the crank-pin d. The part b terminates in a hook.

F is a slotted standard adjustably secured 0 to the plow-beam by means of the bolt 0.

G is a link, pivotally secured at its lower end by a bolt, f, to the lower end of the standard F, and at its upper end it is pivotally secured at g to the pitman.

In practice the revolution of the plo\vwheel when traveling upon the ground conveys mo tion to the pitman, the hooked end I) of which will travel in a path indicated by the dotted lines in the drawings. This path shows that 0 the point of the hook in descending reaches back of the cutting-edge of the colter. Then, after having reached its lowest point, it moves directly forwarduntil it is some distance in front of the cutting-edge of the colter, when it 5 changes its direction in an upward course, which carries it near the under side of the plow-beam. The change of direction in the motion of the hook is well defined and differs materially from the circular motion of the other end of the pitnian, and the path produced by said motion is the one I think best adapted to effect the purpose in view-that is, freeing the colter from roots, stubble, or weeds which may accumulate thereon in plowing.

The advantages I get with my improved 5 5 construction are First. The cleaner does not form an obstruction back of the plow-wheel, as the pitman is now raised on a line with the plow beam.

Second. The hook frees itself very readily from the debris it withdraws from the colt-er, as the pitman tilts considerably at the upward motion of the hook, which at the same time is very abrupt and quick, owing to the pivotal point 9 being quite close and considerably 6 5 above the crank-pin (Z.

Third. The adjustable standard F allows of the raising or lowering of the pivotal point 5 of the pitman, so that its relative position toward the crank-pin may be maintained whenever the plow-wheel has to be raised or lowered according to the varying conditions-in plowing.

Fourth. The path of the hooked end of the pitman is the most appropriate for effecting the purpose and saving power, as the hook withdraws from the colter in a direct line, frees itself quickly i n ascending and in descending, does not bundle the debris, but just goes behind the edge of the colter and withdraws the debris from the point of attachment. This result is owing to the combined influence of the action of the link and the position of the pivotal point 9, which is placed rather close to the crank-pin, so as to give to the hookspath the desired elongation. Thelength 8 5 and curvature of the hook assist in prevent ing the bundling of the dbris.

Fifth. The construction of the pitman,which is made in two pieces adj ustably secured together bya single bolt, whereby the same may be readily adjusted in length to suit all the changes produced bythe various adjustments of the parts of a plow, or to adapt the dcvic for different styles of plows.

What I claim as my invention is 1. In a colter-cleaner, the pitman E, provided at one end with a downward bend, h, directly attached to the plow-wheel, and the cleaner-hook b at the other, with a moving fulcrum between the two, and adapted to oper- IOO ate approximately at the height of the plowbeam and in general line with it, substantially as and for the purpose described.

2. In a colter-cleaner, the pitman E, in combination with thelink G and standard F, which latter is adjustably secured to the plow-beam and forms an adjustable fulcrum for the link G, substantially as and for the purpose described.

3. In a eolter-cleaner, the combination of the pitman E with the link G, adjustable standard l and adjustable cleaner-hook b, all arranged and combined as described, and for the purpose of giving the ;necessary adj ustments to apply the device to plows of different styles or to accommodate it to varying adjustments of the same plow, substantially as de scribed.

l. The colter-cleaner herein described, consisting of the pitinan E, provided at one end with a downward bend, it, and at the other with the hooked end I), in combination with the link G, having an adjustable fulcrum at one end and a pivotal connection with the pitman E at the other end, said pivotal connection being comparatively close to and above the crank-pin connection of the pitman with the plow-wheel, all combined, arranged, and operating substantially as described.
